An Air Force Office of Scientific Research-sponsored group of researchers at the University of Michigan have invented a new type of magnetron that could lead to improved radar systems. According to Dr. Ron Gilgenbach at the university, “This invention should make it possible to develop more compact magnetrons that operate at higher power and higher frequencies.” He said the work exploited “some plasma physics principles … as well as an innovative, new geometry to overcome the physical limitations of conventional magnetrons.” (AFOSR report by Rebecca Rose)
The use of a military counter-drone laser on the southwest border this week—which prompted the Federal Aviation Administration to abruptly close the airspace over El Paso, Texas—will be a “case study” on the complex web of authorities needed to employ such weapons near civilian areas and the consequences of agencies…
